ARM allmodconfig fails because of the addition of the FMAN driver:
drivers/built-in.o: In function `dtsec_restart_autoneg':
binder.c:(.text+0x173328): undefined reference to `mdiobus_read'
binder.c:(.text+0x173348): undefined reference to `mdiobus_write'
drivers/built-in.o: In function `dtsec_config':
binder.c:(.text+0x173d24): undefined reference to `of_phy_find_device'
drivers/built-in.o: In function `init_phy':
binder.c:(.text+0x1763b0): undefined reference to `of_phy_connect'
drivers/built-in.o: In function `stop':
binder.c:(.text+0x176014): undefined reference to `phy_stop'
drivers/built-in.o: In function `start':
binder.c:(.text+0x176078): undefined reference to `phy_start'
The reason is that the driver uses PHYLIB, but that is a loadable
module here, and fman itself is built-in.
This patch makes it possible to configure fman as a module as well
so we don't change the status of PHYLIB in an allmodconfig kernel,
and it adds a 'select PHYLIB' statement to ensure that phylib is
always built-in when fman is.
The driver uses "builtin_platform_driver(fman_driver);", which means
it cannot be unloaded, but it's still possible to have it as a loadable
module that gets loaded once and never removed.

Applied, sorry I didn't catch this but nobody else was even attempting
to review that huge patch series so I did the best that I could... :-/
